Check out the charts below. These are the body measurements we use when we design our products. If your measurements are in between two sizes we recommend you to go for the bigger size if you want a looser fit, and the smaller size if you prefer a slimmer fit. For more tips and help we recommend you to visit our complete size guide page.

When launching this experimental product, we could never have foreseen how popular they would become, selling out repeatedly after each re-stock. Apparently there were more than us in need of super-light and ultra-warm insulation pants for colder days. The 1000 fill power platinum down is unique in its ability to insulate, but no-one has been crazy enough to ever use it for a pair of pants — until now. The sensation of warmth is immediate when you put them on. The down is also treated for water resistance which makes it more durable, while keeping you warm and dry even in the wet. The shell material is a Japanese ultra-lightweight DWR-treated 34 g/m2 ripstop nylon. The side zippers makes it possible to put them on and take them off them without removing your shell pants.

Layering is everything

Every product we create, down to the very last detail, is part of a technical layering system — finely tuned to perform during demanding physical activities in shifting alpine conditions.

A complete Stellar Equipment System will transport moisture away from your body, fast and efficient, while keeping you warm and dry at all times. It also permits materials to move freely over each other for maximum comfort, function and freedom of movement.

Layering is everything when it comes to high performance outerwear: Performance, comfort, energy, safety and durability.
